' Application aledMawh 31, 1882. (No model.)

To all whom z'tmay concern:

Be it known that We, SAMUEL W. MARTIN and CHARLEs D.' HAUK, of Springfield, in the county of Clarke and State of Ohio, have in- 5 vented certain Improvements in Stop-Valves,

of which the following is a specification.

Our invention relates to astop-valve wherein the valve proper is mounted on avibratory arm provided with a projecting journal; where'- Io by it may beoperated positively on the outside ofthe body.

Ourimprovement is designedjmore particularly for use in connection with three-way valves designed to discharge through one or 15' the other of two throats, as required;l but the improvements may be applied withequal facility to what are commonly known Has straight-way valves, having a single inlet aud a single outlet opening:

2o The invention consists in the improved man ner of inserting and operating thevibratory valve and inminordetails. The drawingsV illustrate a three-way valve adapted for use in connection with lifting-pumps to direct the 2 5 Water to the surface or to a reservoir, as may be required.

Referring to the accompanyingV drawings, Figure l'represents a vertical central section through our valve. Fig.2 is a side elevation,

3o illustrating the manner in which the valve is used iu connection with a lift-pump. Fig. 3 is a perspective view of the valve .proper detached from the case or body. Fig. 4 is a perspective view of the valve case or body with 3 5 the valve removed.

In constructing our valve we first provide a case or body, A, which maybe of any suitable form and configuration, having an inlet-neck, a, at the bottom and an outlet-neck, b, at the 4o top, and a second outletneck, c, on one side.

The body is provided, to admit Vthe insertion v of the valve, with a large openingfd, in the corner or angle between the two outlet-necks,

as'plainly represented in Figs. 1 and 4,and

45 has on the outside, around the edges of the opening, ilat faces e.

The valve proper consists, as shown in Figs.

l and 3, of a vihrato'ry arm, f, provided at one end with two valve disks or faces, g, on oppo- '5o site sides, and supported at its opposite end Vposition by inserting the spindle k endwise 'through the plate and arm, as'shown in Figs.

l and 3, and passing av fastening-pin, m, 6o through the arm and the spindle, as represented. The pin m serves both as a means by which the rotation of the spindle is caused to vibrate the arm, and also as a means of hold- Ving the spindle against end motion. 65

In assembling the paris the vibratory arm is first applied'to the plate l, as shown in Fig. 3, after which the valve is inserted through the opening d in the body, and the plate l secured or bolted firmly against the outside of 7o vthe body in such manner as to close tightly the opening d and prevent the escape of 'water through the same. When the parts are thus assembled the angular end of the spindle or rock-shaft k is exposed on the outside oi' the 75 valve, so that it may he operated by an arm, lever, or other device applied thereto, the preferred device being au arm, p, applied as represented in Fig. 2.

By means of the outside lever the spindle 8o may be caused to vibrate the valve-arm in such manner ,as to throw' the valve-plates Yop-l posite the outlet-throat b or the outlet-throat o, and close one or the other, as may be required.- l 85 The outlet-throats b and c may be cast in one piece with the body A, and may have at their inner ends suitable seats or throats for the valve-plates g to close upon; but in order to facilitate the accurate tting of the parts, 9a and to admit of the wearing-surfaces being rounded, it is preferred to provide the valve with removable seats g, of any approved construction, for the valves g to rest against. In the .'drawings, Fig. l illustrates the preferred 95 method of applying these removable throats, each throat consisting of an outwardly-flanged ring inserted through the end of thebody on the outside and supported upon allange or ledge, r, being secured in place by means of a roo a escaneo threaded outlet-neck screwed into the body from the outer side, as shown.

In order to prevent the leakage of water past the outer edges of the valve-seats q, rnbber or other packing-sheets s and t may be placed on opposite sides of the same, as shown in the drawings. When the packing-sheets are thus supplied and the tubular neck screwed inward the packing will be compressed and the edges of the valve-seat held tightly between them.

The valve plates or faces g may be of any suitable construction. It is preferred, however, to make them, in the manner represented in Fig. 1, by mounting disks of vulcanized rubber or equivalent elastic material t on the cuter faces of metallic supporting-plates u, which latter are provided with central necks, o, itting loosely into an openin g in the end of the vibratory supportin g-arm f, the parts being held together by means of a central bolt, w, passing through both plates and their elastic faces. This construction permits the valve-plates to rotate independentlyv of each other and to move independently of the arm to a limited extent, in order that they may adapt themselves to the position of the seats or throats.

When the device is used in connection with a pump delivering through an elevated pipe it is desirable to provide means of preventing the water from dowing backward through the valve, and for this purpose I provide the device, in its side, with a check-valve, ar. The valve represented in the drawings consists of a flexible sheet of leather or rubber, having its central portion cut loose from the remainder and provided with a metallic plate or weight, which serves the double purpose of a weight to close the valve and of a support to prevent the ilexible material from giving way under the pressure to which it is subjected. The outer edges of this valve-sheet are inserted between the outlet-neck and the valve-seat q, and serve as a packing between said parts.

It will be seen that when the main valve is in the position represented in Fig. l the water ascending through the neck a will be compelled to pass through the side delivery, c, the valve at such time closing the outlet b. When, however, the spindle is turned and the main valve thrown downward in the direction indicated by the arrow in Fig. l, the neck c will be closed and the water compelled to escape through the upper outlet, b.

It will be observed that the valve is forced firmly to its seat,under either of its two adjustments, by the pressure of the water'within the body.

In making use of my valve in connection with a pump it is ordinarily employed as-represented in Fig. 2, in which C represents thc pump-cylinder, D the pipe leading directly to the surface, and E the lateral pipe extending to a reservoir or elsewhere.

The valve A is applied at the junction of the pipes C and D and E, and an operatingrod, F, extended from the valve through the platform G at the top ofthe well, so that it may be operated by the attendant standing thereon. By simply moving the rod the attendant is enabled to adjust the pump furthe delivery of the water at the surf-.ice or elsewhere, as may'be required.

We prefer to locate the valve, as represented in the drawings, beneath the surface of the water within the well, whereby it is prevented from being frozen up or disabled during the winter.

It is manifest that the valvebpcratng spindle may be set. in ears formed upon the body at the sides of the opening d, in which caso the external plate would serve only as ameans of covering and closing the opening; but the construction represented in the drawings is for various reasons preferred.

When applying our improvement to a straight-way valve it is only necessary to omit one of the delivery-necks and construct the body of the valve with a closed side, as indicated hy the dotted line W in the drawings.

Having thus described our invention, what we claim is- 1. In combination with the body A, having the inlet and the two outlet openings, the in ternal vibratory arm provided with two valves, substantially as described and shown.

2. The combination of the body provided with inlet `and outlet openings, the seats or throats at the inner ends ofthe outlet-openings, and the vibratory arm provided with the two valve-surfaces capable of a limited motion independent of the arm.
